The caffeine in coffee can also contribute to stomach pain through several different means. Caffeine stimulates the central nervous system, which can cause the stomach to produce excess stomach acid. This excess stomach acid can contribute to gastritis or ulcer formation.
The caffeine, oils and acids in coffee irritate the stomach lining, which can cause excessive production of hydrochloric acid leading to a variety of digestive ailments. Decaf, which contains the same oils and acids as regular coffee as well as traces of ethylene chloride, brings on the same increase in stomach acid. Drinking coffee on an empty stomach produces an even greater increase in stomach acid, and can cause stomach pain almost immediately in some people.
